president obama didn't make it happen. it was republican senators saxby chandlis. tonight the fbi is finally in tunisia to question in person the man caught on video during the attack. how can two republican senators get done in two days what the president of the united states could not get done in weeks? senator lindsey graham joins us. good evening, sir. >> good evening. >> greta: what what is the explanation? i would think with all due respect to the united states senate that in you are the president of the united states you have more muscle than you do if you are a member of the u.s. senate and the fbi has been trying to talk to this man in tunisia. tunisia has said no and then you and senator chandliss got into it two nights ago and voila, you could talk to him. >> i wrote a letter three days ago to the ambassador, u.s. ambassador, tunisia ambassador to the united states saying this is a defining moment in our relationship. i know tunisia well. i know the prime minister. and within two days we were able to get the fbi on the ground. i want to thank the tunisia
